Extraction of Physiological Indexes Reflecting Fatigue Induced by Long Time Seating

Abstract

The purpose of this study was extraction of physiological indexes reflecting fatigue induced by long time seating. Consequently, the following findings were obtained. 1) The association with the subjective fatigue (SF) of the whole body was suggested higher in the order of SF of lower thigh, lumbar, hip, thigh. 2) Bioelectrical impedance (BI) showed different variation in lumbar, thigh or lower thigh. 3) Estimation accuracy of SF of the whole body by physiological indexes was improved than before by using BI and heart rate variability (HRV) in the explanatory variables.
